That's perfectly understandable, as the DOS is loaded by the first disk, so it won't recognize the second. Not sure if any OS can manage disks from other DOSes...

However what I think Brana is asking is for some kind of instruction list to follow. I wouldn't know how to do it either, without a manual for the disk where the file is.

I suppose there must be commands to inhibit auto-run and to load a program at a certain memory location (provided it is not large enough as to make this impossible or make returning to BASIC impossible). After it has been loaded a normal CSAVE "name", A#xxxx, E#yyyy where xxxx and yyyy are the starting and ending memory locations where the program resides will work for saving it on tape (an MSDOS tap file with Euphoric).

Or much better and easier: use Scott's utility to drag the file onto an MSDOS tap file. Pitty you cannot drag it back onto a disk

After this is done you need to boot with the Sedoric disk and issue a CLOAD "name",A#xxxx, which will load the tap file. Then save that memory area to disk with the corresponding instruction, putting back the old infos that indicate auto-run and location to load in memory (something similar to SAVE, but I don't know the syntax)...

Can anybody fill in the (numerous) gaps so Brana can just type the instructions and get it working?

Anyway this issued another problem and it is that there *should* be an easier way to do this..

Well just to let you know, I've made some progress with writing to disk files. I've just about got the code working to save a file to an OricDOS disk although there's still some work to do to get it fully working.

Hopefully I'll have it done in the next few weeks, time permitting then I can move onto saving files to SedOric disks.
